As computers based on Microsoft's new tablet PC concept starts to appear in earnest, hardware manufacturers are starting to push the concept as ideal for mobile computing applications.

However, the definition of a true "tablet" PC is already becoming blurred. The specification uses a special version of Windows XP, Microsoft's mainstream desktop operating system, which includes handwriting recognition, and comes as standard with a hard disk and other peripherals associated with full-specification notebooks.

However, some so-called "tablet" computers use the more compact Windows CE OS instead, and may lack local storage options, being intended mainly for use as terminals on local- or wide-area networks. Microsoft itself has developed a kind of "alternative tablet" specification called Mira for such units, and a full launch is expected next year.

Meanwhile, some manufacturers of what are effectively large-format PDAs or handhelds are promoting these, too, as tablet computers.

 

One of the first "genuine" tablet PCs to be launched into Britain's mobile data market is PaceBlade Technologies' PaceBook (above), which is being marketed in Europe by mobile solutions specialist 3C UK, of Brierley Hill, West Midlands.

A key feature is a rotation button that swivels the screen so it can operate in portrait or landscape mode. The touchscreen uses either stylus or finger touch input, or relies on hands-free voice recognition. A wireless keyboard transforms it into a notebook, and there is an optional stand so that it can operate like a desktop computer.

Specifications include a Transmeta Crusoe processor, 128MB SDRAM (upgradeable to 640MB), 20GB to 30GB hard disk a 12.1in XGA TFT-LCD display with a touchscreen overlay. It operates with Windows XP or 2000.

Meanwhile WalkAbout Computers is one of the first computer manufacturers to develop a rugged tablet PC that meets Microsoft's tablet PC rules. Its Hammerhead model will run Windows XP Tablet PC Edition, which means it can run full Windows-based applications using a pen or speech, annotate documents, and create handwritten documents for reference or conversion into text.

The Hammerhead has built-in wireless connectivity, on-screen keyboard and hot-docking support.
